Product Description
1.1
Key Features and Key Characteristics
The R&S
RT-ZD01 high voltage differential probe is designed to safely measure
high-voltage floating circuits using a grounded oscilloscope. The probe extends
the measurement capability of oscilloscopes in measuring electronic power con-
verters, inverters, motor speed controls, switch mode power supplies and many
other applications.
The R&S
RT-ZD01 high voltage differential probe conforms to the safety require-
ments for CAT III measurement instruments and pollution degree 2 according to
IEC 61010. The maximum working voltage is 1000 V (RMS) between each input
lead and earth ground. This limit applies for all attenuation settings.
1.2
Measurement Categories
To ensure safe operation of measurement instruments, IEC 61010-2-030 defines
particular safety requirements for testing and measuring circuits. The standard
introduces measurement categories that rate instruments on their ability to resist
short transient overvoltages that occur in addition to the working voltage of the
instrument and can exceed the working voltage many times over.
Measurement categories are distinguished as follows:
●
O - Instruments without rated measurement category
For measurements performed on circuits not directly connected to mains, for
example, electronics, circuits powered by batteries, and specially protected
secondary circuits. This measurement category is also known as CAT I.
●
CAT II:
For measurements performed on circuits directly connected to the low-voltage
installation by a standard socket outlet, for example, household appliances
and portable tools.
●
CAT III:
For measurements performed in the building installation, such as junction
boxes, circuit breakers, distribution boards, and equipment with permanent
connection to the fixed installation.
